“…The slight difference is attributed to the limited ion-exchanged properties of muscovite. Although they share a similar tetrahedral–octahedral–tetrahedral sheet structure, less ion substitutions (mainly Al 3+ /Si 4+ and Mg 2+ /Si 4+ ) happen in the muscovite and smaller number of balanced cations are adsorbed in the interlayers …”

Hydrogen Diffusion in Clay Slit: Implications for the Geological Storage

We determined the self-diffusion coefficients of hydrogen in clay (montmorillonite) nanopores using molecular dynamics under subsurface conditions. We explored the effects of temperature, pressure, pore size, moisture content, and salinity. Our results show that the self-diffusion coefficient of hydrogen is on the order of magnitude of 10–8 m2/s. The diffusivity of confined hydrogen increases moderately with temperature and slit aperture but declines with pressure. The estimated density profile suggests that only one dense layer of hydrogen molecules is adsorbed near the slit surface. The distinct diffusion coefficients in the parallel and perpendicular directions to the basal surfaces confirm the confinement effect of the substrates. As the volume ratio of hydrogen increases, the existing pattern of hydrogen changes from a droplet to a layer sandwiched by the aqueous solution. The water bridge will act as a piston for the hydrogen droplet and impede hydrogen diffusion. However, when the hydrogen and brine form a stratified structure, the self-diffusion coefficient of hydrogen sandwiched by two brine films is similar to that of confined pure gas at the same pressure and temperature conditions. If the brine salinity reaches some extent, part of brine and hydrogen molecules will mix as a new phase, which slightly inhibits the hydrogen diffusion. This work provides a better insight into hydrogen diffusion through the clay nanopores, which is critical for reliably assessing the risk of hydrogen leakage through caprocks.

“…Controlling the microstructure to improve the toughening e ciency of rubber is worth learning in the eld of transparent MABS resin. Additionally, the mechanical performance of ABS resin could be optimized by introducing additives such as graphene nanosheets and carbon nanotubes [28][29][30][31]. Unfortunately, the distinction in refractive index between the additive and the matrix is detrimental to the transparency of the composite [32,33].…”

Methyl methacrylate-acrylonitrile-butadiene-styrene (MABS) was obtained by blending the rubber phase with matrix resin. Matching the refractive index was crucial for transmittance in MABS resins. Additionally, the superimposed effect of particle size and the interfacial area further determined the MABS resin transparency. The MABS resin with a rubber particle size of 201nm had a transmission of 88.9% when the refractive indexes of the two phases were close. By utilizing a bimodal distribution of toughened particles in the phase domain structure, the rubber particle size could be altered while maintaining control over the interfacial area. It resulted in an increase in the transmittance of the MABS to 90.1%. The analysis of mechanical properties and morphology shows that the phase structure with a bimodal distribution of toughened particles is also beneficial to the impact and tensile strength of MABS resin. When toughening particles with a size of 73nm and 304nm were mixed in a mass ratio of 60:40, the impact strength was 145 J/m, the tensile strength was 47MPa, and the elongation at break was 20%. And the study investigated the impact of rubber content on the properties of transparent MABS resins.
